Company Overview

Pieris is a biotechnology company based in Boston, Massachusetts that could potentially be entitled to receive development, regulatory, and sales-based milestones from its 4-1BB bispecifics immuno-oncology assets partnered with Pfizer (formerly Seagen), Boston Pharmaceuticals, and Servier. In addition to the milestone potential, Pieris would be eligible for sales royalties on the same partnered programs if they ultimately are approved for commercialization. The Company is seeking potential acquirers for its remaining preclinical and clinical assets.
